The JBO Thread Ring Gauge (GO) in Metric Fine is a precision tool designed to verify external thread diameters with consistency. It is ideal for engineering shops, quality control teams, and maintenance crews that need quick, reliable checks of threaded components. Tailored for right-hand M9 x 0.75 threads and a 4h tolerance, this GO gauge helps confirm parts meet exact standards without guesswork.

Crafted from hardened steel, it provides durable performance in demanding environments and resists wear over time.

• Precise GO gauge for metric fine threads: Quickly verify external thread diameters to ensure M9 x 0.75 components conform to the 4h tolerance class, speeding up inspection without guesswork.
• Hardened steel construction for durability: Withstands frequent use in busy workshops and resist wear from threaded parts, delivering long service life and consistent performance.
• User-friendly design for fast identification: Easy engagement with parts and clear pass/fail indication, reducing inspection time and operator errors.

This gauge streamlines quality control by delivering clear, repeatable results that operators can trust. Its robust construction minimizes downtime and replacement costs, while its straightforward operation supports faster inspections, improved part fit, and higher overall precision across manufacturing, assembly, and maintenance workflows.
